New York is above considering any American city its worthy rival.
Boston probably comes closest, because of the Red Sox and Patriots, and Philly a clear but distant second on the sports front. If you're talking about more incohate cultural factors, I would say DC and San Fran actually loom much larger in our eyes than LA and Chicago. LA is not really what we would consider a "city", and Chicago is just that odd place that operates under the collective delusion that upside-down tomato casserole is somehow "pizza", which of course it is not.

When I lived in Philly, we definitely considered NYC to be our main rival in everything. Pittsburgh was mostly an afterthought, except when it came to hockey I guess. And upside-down tomato casserole was still, of course, an object of well-deserved derision.
And yet Chicago is so much more American than New York.. which is increasingly unique... and unrepresentative of the nation as a whole.
Are you really trying to play the "Real American" card here? For shame.
I guess I am, if you wanna define it that way.
